Abstract: A cabinet for warning blink lights is built up of two identical half parts comprising a shroud (1), a bottom (2) with a holding part (3) for a stand or column, said half parts also being provided with a projection (12) and corresponding recess (13), and also a high internal rib (6) and a cooperating low rib (7) which have a projection (9) and a recess (10) at their respective end surfaces, thus allowing the half parts to be interlocked, in that the projection (12) is engaged with the recess (13) and the projections (9) go down in the recesses (10). Any mutual displacement between the half parts is thus prevented.In addition, a bolt assembly is possible through a tubular stub (11), said stub having end surfaces which slope upwards towards the top of the half part, whereby the half parts are effectively secured together when the bolt is tightened.
